Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] like image 3 and Figure 4 Shown, the vectorized realization method of the vector processor-oriented two-dimensional matrix convolution of the present invention, its steps are:
[0028] S1: Input convolution matrix A and convolution kernel matrix B; Convolution matrix A and convolution kernel matrix B are transported to vector storage unit and scalar storage unit respectively by DMA controller;
[0029] S2: Multiply one row of elements of the convolution matrix A and one element of the convolution kernel matrix B corresponding to one row of elements after broadcasting, and the result of the multiplication is accumulated by an accumulation register initialized to 0;
[0030] S3: Take out the first K-1 elements of a row of elements taken out from the convolution matrix A in step S2 by shuffling instructions to the vector proce...
